What appears to have happened next were efforts by the SRF to increase skepticism over sugar’s link to heart troubles. In 1967, an SRF-funded report led by Harvard nutrition professors was published in the New England Journal of Medicine. The report reviewed the available evidence that linked various nutrients to heart disease and argued that epidemiological and animal studies that linked sugar with heart disease were limited, and suggested the available science wasn’t up to snuff. The review also highlighted studies that linked saturated fat to heart problems, without the same critiques. The review was published in the journal without disclosing the sugar industry’s funding or role in making the study happen in the first place. (Later, in 1984, the NEJM began requiring disclosure of conflicts of interest.)
